Appncatio mea Augsfzv, raza ossei-m1 No. 659,576.1

This invention relates to railway cars and especially to uncoupling vdevices therefor. The main objects of the invention are to provide an' improved form of uncoupler .3 device and especially to produce a. better form of connectingmeans or joint adapted to provide for limited flexibility in an uncoupler bar of the sectional cantilever type comprising two parts extending oppositely :d 'from a point adjacent to the fulcr'um. l Further objects are to provide a simplified and strong construction adaptedffor ready manu- V facture and maintenance at a low cost;A and to provide such a` device adapted for ready assemblage and interchange ot' parts.

iAn i'lllustrative embodiment 4of this invention is shown in the accompanying draw= ings, in which: p

Fia 3. In the construction shown in the drawings, the car 1 andcoupling device Q, including thelift pin 3, are shown substantially in accordance with the present usual construction. The 'medially Ysupported uncoupling lever comprises two separate and detachable substantially alined arms 4 and 5 which normally areV voperatively secured together and to the pivotally mounte box-like supporting connector 6. Arm, 4 is tliehandle arm and arm 5 is the vpin operating arm' or lift member. The support or joint member v6 is carried by the horizontally facing pivot bracket 7, which is rigidly secured to the adjacent frame beam S of the car end and provided with a horizontal pivot 7.

Said lever is normally disposed inl a nearly horizontal position, and is rockable in-approximately a vertical plane sutliciently to lift the knuckle lock 3 and so uncouple the cars whenever downward movement is applied to the handle arm 4. Said arm is preferably disposed mainly beneath @e lowermost step 9 of the ladder on the nd is a section on the line 55 of of the car, so asv to be protected from 'the accidental `operati-on, as will be understood. l

The arm connector' or rocker 'rfamefG may well be inade 'as a ste'el casting' of rectangular shape. It is provided with a Central tranverse pivot hole 10 to receive the pivot 7', and with a pair ot" varm sockets 11 andk 12 on the upper and under 'sides respective of t'hehorizontal central partiti/en Y12? The 'and partially intersecting said hole. arms 4 and 5 overlap somewhat and are notched on their v"adjacent V'edges as at 14 and 15 respectively in registry with said hole 10 so as to be loclrecl'in place by said pivot 7 when the vvdevic'eis assembled for use. of'pivot 7 holdsthe box "6, in place against the bracket shoulder 18. l

The upper "aperture 11 receives arm 4 in substantially Vsnug fitting' relation sol as'to hold the arm rigidly, but the ylower apen ture 1:'2 isl longitudinally flared both `horizontal-ly and vertically in both vdirections from 'the' middleware; the 5 Se- -cnred against longitudinal Vrn(')venien't by the pivt -in 'nen-rigid `rennen. This ae- CI'nn'd-ltes lthe"alr 5 to all niTIV'I-ial op@ l@rating movemenrsbf the' car and coupling. In order to 'pre/vent an unnecessary or undesirable degree or downward mv'ern'entoff arm 4, as in raising the knuckle lock "3, `a

'stop shoulder 19 is provided on the 'back side of Vtheconnector 6 to 'engage "o'r rctmta'ct with the fixed shoulder 20 on bracket 7. The handle arm is -`thus dennitely limited in its swing when pushed downwardly and thus vtenids to avoid accidents. Moreover the lift Varm is prevented from swinging around` too far Vand possibly striking "the operator on the head. Said bracket '7 is held rigidly by bolts 21 in the bracket ears 22, as will be understood. l

Vhenever it is'desired to take the device apart, as for renewal of partsvor for any other reason, the cotter 16 is removed. Then the connector 6 and lever arms carried thereby may be .slipped otl bodily from This releases the arms 4 and 5 which may then be removed. The reverse operation may be followedin assembling the device.

Although but one specific embodiment ofv this invention is herein shown and described, it is to be understood that numerous details ofv the construction shown may be al- '7x0 A' Cotter .pin 16V inthe perforation 1'( v to l tered or omitted Without departing from the spirit of theinvention as 'defined by the following claims.

I claim:

'1. An uncoupling device comprising in combination a joint member, a stationary fulcrum pivot whereon said member is oscillatably supported and a lever including a handle arm andan operating arm disposed oppositely and having their adjacent ends arranged one above the other on opposite adjacent sides to receive saidV pivot which serves to lock the said parts all together in effective relation.

3. An uncoupling device comprising in combination a joint member, a `ulcrum whereon said member is oscillatably supported and a lever including a handle arm and an operating arm disposed oppositely and having their adjacent ends detachably securedY to said member, the latter being apertured in one direction to receive said arms endwise in mutually overlapped relation and in another direction to receive said fulcrum which is in theform of a pivot positioned horizontally, said arm ends being` notched on their adjacent sides to receive said fulcrum endwise between them, which serves to lock said parts all together in eective relation.

4. An uncoupling device comprising a connector having a horizontal pivot receiving aperture and a pair of arm receiving apertures ture one above and the other below and intersecting said aperture, in combination With a supporting fulcrum pivot fitting in the corresponding aperture, a handle arm fitting disposed crosswise of said aper-V ing aperture and a pair of arm receiving lapertures disposed crosswise of said aperture one above and the other below and inter. secting said aperture, in combination with a supporting fulcrum pivot fitting in the corresponding aperture, a handle arm fitting snugly in one of the other apertures and an operating` arm fitting loosely in the other arm aperture which is flared both ways from the center, said arms overlapping each other and being notched adjacently to receive said pivot whereby thej7 are locked in place against endwise movement when the device is assembled.

6. An uncoupling device comprising a connector having a horizontal pivot receiving aperture and a pair of' arm receiving aperturesdisposed crosswise of said aperture one above and the other below and intersecting said aperture, in combination with a supporting fulcrum pivot fitting in the corresponding aperture, a handle arm fitting in one of the other apertures and an operating arm fitting in they third aperture, said connector having a stop Vshoulder to limit its movement in thek uncoupling direction and the operating arm being fitted loosely in its aperture to accommodate the necessary lateral and vertical movements of saidl arm incident to car or coupler movements.

7. In an uncoupling device comprising a connector having a horizontal pivot receiving aperture and an arm receiving aperture disposed crosswise of said pivot aperture, in combination with a supporting fulcrum pivot fitting in the corresponding aperture, and an arm 'fitting in the other aperture, said arm being notched to receive said pivot whereby it is locked in pla-ce Vwhen the device is assembled.
